Instantaneous acceleration contains information
about the acceleration at every moment in time.
Graphically, it is the tangent slope at a point
on an v-t graph. It is also related to the curvature
of an x-t graph. Lets you generate a-t graphs
Instantaneous acceleration is very important because it
will ultimately be directly related to forces
Can acceleration and velocity point in different directions?
You can be moving in one direction and accelerating in another
“I’m driving south at 40m/s and come to a stop in 10 seconds.
What is my average acceleration? Treat South as +”
Answer: (0-40)/10= -4m/s2 (this is north)
